To be fair, some of the bigger things (DPF and CP4) haven’t failed yet. But...they were due. I think some of the problems get overblown online, but I’ve known a few guys with failed CP4’s. The 2011 was the first year of the LML and the first year of the SCR/DEF system. First year is never good for reliability.
I almost forgot, it would blow out massive clouds of white ‘smoke’ (actually unburned fuel vapor) from the tailpipe when in a regen. Dealer said it’s normal but it isn’t. It is a degraded 9th injector. Good times.
